What is the next number in the series: 20, 10, 10, 15, 30, ...?
Answer:
75
This pattern functions by multiplying the sequence terms by consecutively increasing values: x0.5, x1, x1.5, x2. The next logical mathematical operation is to multiply 30 by 2.5, returning 75.
2362
Identify the next term in the sequence: 16, 8, 8, 12, 24, ...
Answer:
60
The terms are determined by multiplying the previous term by 0.5, 1.0, 1.5, and 2.0 sequentially. Extending this logical progression, the next multiplier is 2.5. Thus, 24 x 2.5 gives 60.
2363
Which number completes the series: 12, 6, 6, 9, 18, ...?
Answer:
45
The series rule applies sequential multipliers of 0.5, 1, 1.5, and 2 to the preceding terms. To uncover the next number, we continue the pattern with a multiplier of 2.5, yielding 18 x 2.5 = 45.
2364
Find the next number in the series: 6, 3, 3, 4.5, 9, ...
Answer:
22.5
The sequence dictates that each term is multiplied by a steadily increasing value starting from 0.5 and going up in 0.5 increments (0.5, 1, 1.5, 2). Following this rule, the next operation is 9 x 2.5, which equals 22.5.
2365
What number comes next: 10, 5, 5, 7.5, 15, ...?
Answer:
37.5
The multipliers applied sequentially are 0.5, 1.0, 1.5, and 2.0. For the next term in the sequence, the multiplier becomes 2.5. Calculating 15 x 2.5 provides the correct answer of 37.5.
2366
Identify the missing number: 8, 4, 4, 6, 12, ...
Answer:
30
Like similar patterns, the multipliers increase by 0.5 at each step. Check: 8 * 0.5 = 4, 4 * 1 = 4, 4 * 1.5 = 6, 6 * 2 = 12. The next multiplier is 2.5, resulting in 12 * 2.5 = 30.
2367
What is the next term in the sequence: 4, 2, 2, 3, 6, ...?
Answer:
15
This series is formed by multiplying the previous term by an ascending sequence of numbers: 0.5, 1.0, 1.5, 2.0. To continue the pattern, we multiply the last term by 2.5. Thus, 6 x 2.5 = 15.
2368
Find the next number in the decimal series: 2, 1, 1, 1.5, 3, ...
Answer:
7.5
The pattern involves multiplying by incrementally increasing numbers: 2 x 0.5 = 1; 1 x 1 = 1; 1 x 1.5 = 1.5; 1.5 x 2 = 3. To find the next number, we multiply by 2.5. Thus, 3 x 2.5 = 7.5.
2369
What comes next in the sequence: 12, 15, 24, 30, 36, 45, 48, ...?
Answer:
60
This interleaved series follows two additive rules. Odd positions are 12, 24, 36, 48 (increasing by 12). Even positions are 15, 30, 45 (increasing by 15). The next term belongs to the even positions, so 45 + 15 = 60.
2370
Find the missing term: 1, 10, 4, 20, 9, 30, 16, ...
Answer:
40
This alternating series uses two very predictable sequences. The first (at odd positions) is a sequence of perfect squares: 1, 4, 9, 16. The second (at even positions) is multiples of 10: 10, 20, 30. The next term continues the multiples of 10, making it 40.
